Sonar is a technique that uses sound propagation to navigate or detect underwater objects. Dolphins use sonar by producing high pitched clicks. When these clicks hit an object, some of the sound echoes back to them. They listen to the echo, and based on the time it takes for the echo to come back to them, they know the distance of the object.
I've been wanting to design something with a dolphin motif forever. Finally, it has found a home :)
This hat comes in a variety of sizes to fit all the kids and adults in your life who love dolphins or catching waves of any kind. Shown in size M in Malabrigo Merino Worsted. I think the dolphin / wave theme is perfectly suited for all the snowboarders on anyone's Christmas list!
